A Brembo GT big brake system built for the Porsche 964 Carrera 2, 1990 to 1994, rear axle. The discs are 328x28mm 2-piece.
GT|A calipers are the two piece design derived from Brembo’s original equipment applications. They are the most straightforward of the GT calipers to install and suit road cars that see occasional track use.
Four piston caliper, used on front and rear axles depending on the application.
Disc face: available cross-drilled or Type 3 slotted. Type 3 slots are the pattern Brembo uses in professional motorsport. They give a strong initial bite and keep the pad face clean as it beds in.
Caliper finish: Black, Red or Silver. The finish is set by the last digit of the part number, so tell us which one you want with the order.
Fitment notes from Brembo: It is not mandatory for kit fitting, however, proportioning valve in rear brake circuit can be replaced with version from Porsche 964 cars originally equipped with 4-piston rear calipers for increased rear brake bias.
What is in the kit: 4 piston aluminium calipers, 328mm 2-piece discs with bells, Brembo pads, caliper mounting brackets, braided brake lines and the fitting hardware. Contents vary slightly by application, so check the part number against the list below.
Part numbers
| Disc face | Base part | Full part number by finish |
|---|---|---|
| Cross-drilled | 2C16017A | 2C16017A1, 2C16017A2, 2C16017A3 |
| Slotted Type 3 | 2CD6017A | 2CD6017A1, 2CD6017A2, 2CD6017A3 |
The last character sets the caliper finish or the line. 1 is black, 2 red, 3 silver, 4 gold, 5 yellow, 6 white, 7 fluorescent yellow. S is a GT-S caliper and R is a GT-R caliper.
Wheel clearance is the thing to check first. A 328mm disc with this caliper needs a specific wheel offset and spoke shape, and the requirement for a GT-R caliper is different from the GT version. Send us your wheel size, offset and make and we will read the clearance drawing against it before anything is ordered.

Brake work is safety critical. Brembo asks that these systems are installed by a qualified technician, and the kit must be checked, bled and road tested to the instructions supplied with it before the car is driven.
